Thank you guys for all replies, before asking more and taking your valuble time i need to read some more.. it would be weird not to be able to do that in such a strong db like PostgreSQL as it is, the reason of question marks is about me, not the db:) .. thanks again..

Using Python and psycopg2:
\df billing_days
List of functions
Schema | Name | Result data type | Argument data
types | Type
--------+--------------+--------------------------+--------------------------------+--------
public | billing_days | TABLE(billing_date date) | start_date date,
end_date date | normal
select * from billing_days('05/01/2017', '05/30/2017');
billing_date
